Pesticide Product, Dealer, and Arborist/Pesticide Business Registration
Product registration and classification
Pesticide products sold or used in Connecticut must be registered with DEEP (following EPA registration). Products are classified as general use or restricted use; restricted-use pesticides may only be applied by or under the supervision of a certified applicator. Questions often ask who may purchase or use a restricted-use product - the safe answer ties use to certification status.
Dealer registration
Businesses that distribute, sell, offer for sale, or hold pesticides for sale generally must register as pesticide dealers. A frequent trap is assuming that selling only general-use products exempts a business, or that a dealer registration substitutes for applicator certification - they are separate requirements.
Pesticide business registration
A business that applies pesticides commercially must register as a pesticide business in addition to employing certified applicators. The business registration and the individual's certification are distinct: a business cannot operate merely because one employee is certified, and a certified individual cannot operate commercially without the business registration.
Arborist registration
Persons who apply pesticides in the course of tree care/arboriculture for hire have registration obligations tied to their arborist activity. Questions test whether arborist pest-control work requires both arborist registration and pesticide business/applicator credentials. Treat these as layered requirements, not substitutes.
Rule of thumb
Separate the product (registered and classified), the seller (dealer), the business (pesticide business), and the individual (certified applicator). Each layer has its own registration obligation.
